Click on Project Admin -> File Manager
Open the scons, scons-src, and scons-local directories. Within each one, open the $VERSION folder. In the scons/$VERSION directory, select the RELEASE.txt file and mark mark it as the release notes in the popup that appears, then save.

If this is a final release of the production branch, select scons-$VERSION.win32.exe and mark it as the default selection for Windows, then select scons-$VERSION.tar.gz and mark it as the default for all other OSes.

In turn, select each of the files (other than the release notes file itself, which is automatically set) in all three folders (and the folders themselves) and specify that RELEASE.txt is to be the release note for that file. Because of the way the page refreshes after clicking Save, it seems to be easier to start at the bottom and work your way up.

FIXME: TEST THIS: You can do multiple releases quickly by opening the File Manager page multiple times in a separate tabs, but if you do, make sure to wait for the page to reload completely in one tab before clicking Save in another. Trying to update multiple releases at once doesn't work, presumably because the session can only handle one update at a time.

Hide previous releases

For a checkpoint release, hide all checkpoints in the same series that are older than this checkpoint.

For a minor or micro release, hide all the checkpoint releases leading up to this release.

For a major release, hide all the checkpoint releases leading up this release AND hide all major and minor releases older than this release.
For each release name you wish to hide, you have to do the following in scons, scons-local, and scons-src:

Click on the gear icon to the left of the package name and select Cut from the popup.

Click on the gear icon to the left of old checkpoints and select Paste from the popup.

Open the directory.

Open the $VERSION folder within the directory.

For each package in the folder, click on the link to download it.

Verify that the files arrived and look reasonable.
